ublk: factor out ublk_init_iod() helper

The code for initializing struct ublksrv_io_desc on I/O dispatch is
largely duplicated in 3 places. Commit 4d4a512a1f87 ("ublk: add PFN-
based buffer matching in I/O path") added support to ublk_setup_iod()
for matching request buffers against registered UBLK_F_SHMEM_ZC buffers,
but missed adding it to ublk_setup_iod_zoned() for zoned requests. Move
the duplicated logic to a new helper ublk_init_iod(). This way, zone
appends can also benefit from avoiding the data copy.
